The objective of this study is to evaluate the impact of a fast-track protocol in a high-volume center for patients with pancreatic disorders. The concept of fast-track surgery allowing accelerated postoperative recovery is accepted in colorectal surgery, but efficacy data are only preliminary for patients undergoing major pancreatic surgery. We aimed to(More)
The repair of DNA double-strand breaks (DSBs) is essential to maintain genomic integrity. In higher eukaryotes, DNA DSBs are predominantly repaired by non-homologous end joining (NHEJ), but DNA ends can also be joined by an alternative error-prone mechanism termed microhomology-mediated end joining (MMEJ). In MMEJ, the repair of DNA breaks is mediated by(More)
Controversy prevails on the impact of preoperative biliary drainage (PBD) on postoperative complications and clinical outcome of pancreatic cancer. We determined whether PBD is associated with increased morbidity and mortality rates after pancreaticoduodenectomy. A total of 131 consecutive patients who underwent pancreaticoduodenectomy (93 jaundiced, 38(More)
This paper presents a general adaptive control scheme for regulating power system devices. The main idea of the paper is to build a fictitiou set of differential equations starting from a function that satisfie Lyapunov's second stability criterion. In such a way, the fictitiou set of differential equations surely converge to a stable equilibrium point. We(More)
The advances in distribution system automation, smart metering and exploitation of microgrids call for the adoption of more flexible options for power flow calculation. This paper illustrates the structure of a tool implemented to deal with time-dependent and uncertain data, as well as changing network structures during time. The focus is then set on(More)
Hexagonally ordered mesoporous silica materials MCM-41 and SBA-15 have been synthesized and loaded with Ag nanoparticles, utilizing both chemical synthesis and ultrashort pulsed laser ablation in liquid. In laser ablation, a silver target, immersed in aqueous suspension of ordered mesoporous silica SBA-15, was irradiated by ultra-short laser pulses to(More)
This paper presents a new way to formulate and solve the distribution system optimal reconfiguration problem. The system equations representing the network topology, power flow equation and objective function equation are transformed into an artificial dynamic model formulated by using only differential equations, on the basis of an error function defined(More)
